Releases

0.5.3​

Bug Fixes​

  • #558 - CustomObject.__str__ rendered "<type> None" after deletion when the type had no primary field
  • #561 - Related Objects link used ?<field>_id= but the filterset only registered ?<field>=; both variants are now supported
  • #567 - Custom object type field changed to undefined in the Add Field page
  • #581 - Skip inherited anonymous export test for CustomObjectTypeField views
  • #587 - Migration 0011_non_deferrable_fk_constraints failed on multi-table-inheritance COTs due to incorrect FK target column
  • #588 - AttributeError: 'CustomFieldChoiceSet' object has no attribute 'get_choice_color' on NetBox < 4.6
  • #592 - Fix Custom Objects API tests for stricter nested related object permissions

0.5.2​

New Features​

Polymorphic Reverse Descriptors

Polymorphic Object and MultiObject fields now support a related_name that exposes a working reverse accessor on the target model instance (e.g. site.co_instances.all()). The form bug that hid the related_name field when the Polymorphic checkbox was checked has also been fixed.

  • #385 / #522 - Polymorphic Object and MultiObject fields: related_name now wires a working reverse accessor on target model classes; form fix for the field being hidden when Polymorphic is checked

Enhancements​

  • #559 - Add slug filter to CustomObjectTypeFilterSet so ?slug= API queries work correctly

Bug Fixes​

  • #353 - AttributeError in __str__ when the primary field was missing from the generated model
  • #369 - Selection fields displayed the raw stored key instead of the human-readable label
  • #370 - Lazy serializer registration via module __getattr__ fixed a SerializerNotFound regression; skip_object_fields guard prevents incomplete serializers from being cached
  • #371 - Tags submitted via POST or PATCH were accepted and echoed in the response but never persisted to the database
  • #384 - AttributeError and false-positive cycle detection caused by stale FK references in cross-COT fields after model regeneration
  • #406 - Bulk import for Object/MultiObject fields targeting models without a name field (e.g. ModuleType) failed with "invalid accessor field name"
  • #428 - Startup warnings from NetBox Branching and Django were not suppressed on Python 3.13 due to message-pattern filter limitations; switched to module-origin filters
  • #470 - ValueError: must be a "TableNModel" instance when saving an object with cross-COT FK fields; caused by stale model class references after model regeneration
  • #491 - Cycle detection in object-field validation failed to traverse polymorphic field edges, allowing circular references that crashed model generation
  • #523 - Deleting a Custom Object Type that had NetBox custom fields attached raised an error; NetBox CustomField references are now removed before the ObjectType is dropped
  • #529 - Selection and multi-selection fields backed by a CustomFieldChoiceSet with colors rendered as plain text; colored badges are now rendered correctly in both the list table and the detail view
  • #535 - Deleting a MultiObject field left its through-model registered in Django's app registry, causing cascade-delete errors on subsequent operations
  • #540 - Clarified Django bootstrap for portable schema export scripts
  • #543 - Tag filter links in the custom object list view returned 404
  • #550 - REST API rejected null for optional Object and MultiObject fields ("This field may not be null.")

0.5.1​

Bug Fixes​

  • #380 - Bulk edit "Select all N objects matching query" only selected the current page
  • #396 - Add permission was not sufficient to access the add URL; change permission was incorrectly required
  • #408 - Cross-COT FK fields missing after server restart
  • #443 - API updates failed for some objects due to non-dict data in generated serializer validate()
  • #477 - Deleting a custom object via the UI raised a ValueError due to through-table entries being included in the delete confirmation queryset
  • #483 - Deletion of objects with M2M relations failed due to stale path_infos on through-model FKs after COT model regeneration
  • #500 - Viewing the changelog for a custom object raised unexpected keyword argument 'user'
  • #503 - FilterSet ValueError caused by ModelChoiceFilter not handling polymorphic objects; replaced with NonPolymorphicObjectFilter
  • #507 - Migration 0011 failed with DuplicateObject on partial re-run and raised errors for long table names
  • #508 - ValueError: Must be 'TableNModel' instance in CustomObjectLink.left_page() due to no_cache=True breaking dynamic model identity
  • #511 - Raised minimum compatible NetBox version to 4.5.2
  • #517 - Mixed-case field names created quoted PostgreSQL identifiers that broke schema cloning; migration 0014 renames them to lowercase
  • #519 - Migration 0011 raised constraint already exists when table_schema was not filtered to the current schema

0.5.0​
